Atomic Theory
Polka!
Dalton
Thomson
Rutherford
Bohr
And Many
More……
Schroedinger
Heisenburg
Used their brains
to venture out
in the realm of
inner space,
And found the world of the atom
was a weird and wondrous place.
Dalton did
experiments and
said…
“I think it’s
clear…
Atoms are tiny,
indestructible
spheres.”
Thomson worked with cathode
rays and said,
“I disagree.”
“A plum-pudding
model,
makes much more
sense to me.”
A new chapter in atomic
theory started to unfold.
When Rutherford played
around,
with atoms made of gold.
When a few of his alpha
particles came bounding
back,
He hypothesized a
nucleus had knocked
them off the track!
Bohr saw spectral lines
for hydrogen and said,
“It seems to
me…
Electrons move in
orbits with specific
energies.”
Heisenberg said,
“Forget it, there’s no way to
know,
The orbit, or a path, where the
electron’s gonna go.”
Schroedinger used lots
and lots of fancy
mathematics,
And made a model of the
atom based on quantum
mechanics.
It had orbitals,
and those are based on
probability
The atom is a fuzzy
blob of pure
uncertainty!
